To fix this, I added a virtual destructor for Proxy in AbstractLayout.cpp.
Will this be an ABI issue? I talked to Rene privately about this when
he was reviewing my suggested changes, and he mentioned the following:
"
That is indeed the correct fix, however that will add a virtual slot
and by extension possibly have some ABI compatibility issues depending
on whether or not that proxy class is actually exposed to any outside
code.
"
Can somebody more familiar with the layout class code comment on
whether or not adding the virtual destructor will be a problem or not?
